Description:
Issue: loss of function of a previous version of LibreOffice.
Pointing to: https://gerrit.libreoffice.org/c/core/+/121914

In versions of LO 6 and higher as tested (see below) it is not possible to select and edit, or copy and paste from collected words in the word completion list box at menu: Tools | Auto-correct | Auto-correct Options | Word Completion.

 A functional practice in LO Writer version 5 has changed to non-functional in LO Writer versions 6 and higher:
	•	The copy function Command+a, Command+c (or right-mouseclick--copy) is unresponsive and does not work to select and copy an entire list from the word completion list box to the clipboard.
	•	The copy function Command+c (or right-mouseclick--copy) also is unresponsive and does not work to select and copy a single word from the word completion list box to the clipboard.
	•	Using Command+c to copy a selection from the word completion list box, the clipboard buffer is empty when attempting to paste (using Command+v) the selection into an existing or new file (e.g., LO_WrdCmpltn_Ver_ SomeNumber_A-Z.odt).

Steps to Reproduce:
Use menu: Tools | Auto-correct | Auto-correct Options | Word Completion -
	1	Open existing working documents from which new words are to be collected and placed in the word completion list box.
	2	Scroll through open existing working documents to collect words; close documents.
	3	Using menu: Tools | Auto-correct | Auto-correct Options | Word Completion check the  word completion list box for collected words.
	4	In the word completion list box: use Command+a, Command+c (or right-mouseclick--copy) to copy the complete list to clipboard --> This function fails.
	5	Paste the complete list from the clipboard into a new or existing master file, (e.g., LO_WrdCmpltn_Ver_ SomeNumber_A-Z.odt) --> This is not possible; copy function will not execute to put a word(s) into the clipboard buffer.



Actual Results:
Observed/actual behavior:
	1	In versions of LO 6 and higher as tested (see below) it is not possible to select, copy and paste from collected words in the word completion list box at menu: Tools | Auto-correct | Auto-correct Options | Word Completion.
	2	Using keystroke combination Command+a, Command+c (or right-mouseclick--copy) in the word completion list box are inoperative.
	3	In the word completion list box -- only one word will highlight (can be selected) at a time.
	4	 it is not possible to select and copy any--one or more--words to the clipboard.
